On days 2, 3 and December 4, 2014 the team traveled to Noordwijck (Netherlands) where the defense of the project was discussed in ESTEC centre, from the European Space Agency. This stage known as Selection Workshop was the first contact with REXUS/BEXUS program, to coexist with different teams for the first time presenting the project idea as us, to a panel of experts. Each team performed a presentation, complete in English, about the project prototype to develop, then face a difficult round of questions from the panel of experts. In this first shows a total of 14 teams, both BEXUS and REXUS were presented, bringing together a total of 68 students. It was a hard work but very rewarding week. Although, since December 18 we were advised that we had been selected to start designing the project. During this week we also carried out other activities in the facilities of the Space Agency, while the teams interacted and shared the experience.
